Main features

Over/Under Temperature Protection

When the temperature goes above or below the set value (high limit or low limit), the SA100L will interrupt or remove the power from the process.
This output can be used for alarm or interrupting power to the heater circuit.
For safety reason, the output will be retained until reset operation is executed even when the measured value goes back to the normal range.
Reset operation can be executed by front key operation, communication, or digital input.

DIN rail mounting type temperature controller

Installable on the DIN rail inside the control cabinet. Removable terminal socket for easy maintenance.

Two outputs can be assigned to control output, alarm output, or analog retransmission output

This instrument can be used as a temperature controller, an alarm, or an overtemperature protection device depending on the output assignment.
